如何在ASP.NET中使用ActiveX控件

我创建了一个ActiveX组件，但无法访问ASP.NET中的ActiveX控件。它使用JavaScript创建ActiveX对象时会出现“Microsoft JScript运行时错误：自动化服务器无法创建对象”错误消息。如何在ASP.NET中使用ActiveX控件

ActiveX组件代码：

using System.Runtime.InteropServices; 
using System.Windows.Forms; 

namespace FirstActiveX 
{ 
    [Guid("465F2D2E-C638-413e-A353-01E09DC4C7ED")] 
    [InterfaceType(ComInterfaceType.InterfaceIsDual)] 
    [ComVisible(true)] 
    public interface IMyActiveX 
    { 
     [DispId(1)] 
     string FirstName{ get; set;} 
     [DispId(2)] 
     string LastName { get; set; } 
     [DispId(3)] 
     string Address { get; set; } 
     [DispId(4)] 
     void Show(); 
    } 

    [Guid("8975D137-9D96-492c-87AE-37D653BADE16")] 
    [ProgId("FirstActiveX.MyActiveX")] 
    [ClassInterface(ClassInterfaceType.None)] 
    [ComDefaultInterface(typeof(IMyActiveX))] 
    [ComVisible(true)] 
    public class MyActiveX : IMyActiveX 
    { 
     #region IMyActiveX Members 

     public string FirstName { get; set; } 
     public string LastName { get; set; } 
     public string Address { get; set; } 

     public void Show() 
     { 
      MessageBox.Show(string.Format("Mr. {0} {1}, Address : {2}", FirstName, LastName, Address)); 
     } 

     #endregion 
    } 

}
